This study implements research-oriented comprehensive chemistry laboratory teaching by combining fundamental education with scientific research training, thus enhancing talent development and promoting educational reform harmoniously. Silver nanoparticles were synthesized using straightforward inorganic chemical reactions, with the color of the resulting silver nanocolloid solution controlled by varying the bromine/silver ratio. This introduction of surface plasmon resonance characteristics into the experimental curriculum increases the experiment’s engagement. The chemical activity of the silver nanoparticles was verified using the classic p-nitrophenol catalytic reaction model. Results indicated that the silver nanoparticles exhibited excellent catalytic performance, approximating first-order reaction kinetics. Additionally, a simple pollutant degradation reactor was constructed using standard laboratory glassware, and homemade silver-embedded filter paper was used for over ten cycles of degradation, achieving a degradation rate of up to 90%.
